need something more aggressive?

let’s look for ec2 cidrs in ohio that have a 13 in them

curl https://ip-ranges.amazonaws.com/ip-ranges.json > aws-ips.json
jq -r '.prefixes[] | select(.region=="us-east-2") | select(.service=="EC2") | .ip_prefix' aws-ips.json | grep 13

then try and get em…

#!/bin/bash
for i in {0..255}; do
	sleep 1
	r=$(AWS_PROFILE=dev aws ec2 allocate-address --region us-east-2 --address 3.13.137.$i 2>/dev/null)
	[ -z "$r" ] && echo "3.13.137.$i is taken" || echo "> 3.13.137.$i is mine!"
done

spoiler alert, they’re all taken D:
